MACHINE DESIGN

Detailed calculations Problems

Three forces, $P=0\mathrm{.}41kN,R=10kN$ and $S=2\mathrm{.}7kN,$ are applied to the machine component ABD as shown. The cross section containing point $H$ is an $1846mm$ rectangle.

$($a$)$ Sketch the stress element at point $H$ showing all stresses

$($b$)$ Draw the Mohr's circle for the state of stress.

$($c$)$ Compute the maximum in$-$plane shear stress.

$($d$)$ Compute maximum and minimum principal stress

$($e$)$ Draw the principal stress element and the maximum shear stress element. Show the stresses in a properly aligned elements
